RADIO STATION SELECTOR.

Application filed July 22, 1924. Serial No. 727,463.

To all whom, it may concern:

Be it known thatI, JAMES P. BURKE, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Radio Station Selectors, of which the following is a specification. I

This inventiohkrelates to radio apparatus, and more particularly to selecting or indicating means used in connection with tuning or receiving devices and the like.

Among the objects of this invention is to provide a selecting or indicating means to be used with a dial or the like in connection with radio tuning or receiving apparatus for indicating or; recording the predetermined setting or adjustment of said apparatus for as many sending stations as the operator may desire, whereby the time and labor incident to tuning in 1s greatly abbreviated.

Another object of this invention is to provide an indicating or selecting means which is readily attachable to a panel board or. the like to be used with a standard or other suitable dial in connection particularly with radio tuning apparatus for recording or indicating the predetermined setting or adjustment of the same for the operators favorite or selected sending stations, the record being readily changed in accordance with new observations or determinations at the will of the operator,

\Vith the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is bad to the accompanying drawings in which like reference characters designate the same parts in the several views, and in which- Figure 1 is a front view of the selecting de- 7 vice, partially broken away.

Fig. 2 is a sectional view taken along the lines 2-2 of Fig. 1.

Fig. 3 is a front view of the assembly of the selecting device and a dial.

Referring now more specifically to the.

drawings, is my station selecting or recording indicator which consists of aplate or the like and is made ofauy suitable sheet metal such as brass. The selector is therefore readily formed preferably in ring form as by stamping or the like, the annular lips '11 and 12 being formed preferably along both the inner and outer peripheries of said ring, said lips being adapted to lie against or in close proximity to a panel board or the like upon which the selector is mounted. The selector is secured to the panel board in any feasible manner but preferably by a ring 13 formed of card board or other fibrous material and adapted to lie against the rear face of the selector and between the lips thereof, and having suitable adhesive material upon the faces. 14 and 15 whereby it is adapted to hold the selector at 1% and the panel board at 15, thus forming a simple neat and effective means for mounting the selector.

Y In the usual radio receiving set, the tuning or adaptation of the apparatus to a certain definite wave length as determined by the sending station whose program it is desired to receive, is accomplished by instruments such as condensers, and the like, which are actuated for adjustment by means of knobs 16 used in connection with a plate or dial 17 having preferably a scale 18 or the like which is adapted, in connection with amark or pointer upon the panel board, to indicate the setting of the instrument. When. however, another station is to be received and the settings changed, no record is left of the adjustments previously made, so that should the operator thereafter desire again to tune in to that station, he wozuldbe compelled to make and determine the adjustments over again, a process which would prove quite troublesome especially if the operator, as is usually the case, is accustomed to receive the programs of a variety of stations. My invention aims to eliminate this condition, while at the same time permitting of suiiicient flexibility and adaptation to suit the needs of the average operator, who usually desires to change the adjustments of his set from time to time in endeavoring to improve the operation thereof. The feature of my invention whereby these objects are accomplished will now be disclosed.

The selector is mounted concentrically with the dial and substantially in the plane thereof so that the main or ring portion thereof lies without said dial and adjacent to the scale thereon. The face of the selecherein after.

releases 'may desire, ach space being adapted to contain the record of the adjustment of the particular instrumentof the apparatus whercwith the selector 18 used for any particular station, a plurality of selectors being provided for each apparatus in accordance with the number of instrument" whose adjustment is to be recorded, the precise man nor of taking the record being described Said record is adapted to be written or printed with pencil or inl: by the operator directly upon the face of the selector, said face being plated with silver or other suitable white metal in order to receive more readily the writing or printing. The radial lines 20 or the like are located along the inner periphery of the selector and preferably in central relation to the divisions as shown. A space 21 is adapted to contain a suitable design or trade-mark and particularly the arrow head 22.

After the adjustment has been made, the coincidence or registry of a line 20 and a line upon the scale 18 is observed, the corresponding number as determined by the scale is read, and said number recorded in the space containing the line 20 together with the code symbol of the particular sending station. Thus, assuming that the apparatus has been tuned in to receive W 5 Z, a registry as aforesaid is seen at 77. The letters W J Z are accordingly recorded- Within the space, together with the number 77. Thereafter if the operator desires to obtain 7 J Z he need merely turn the knob until line 77 upon the scale 13 coincides with the line 20 in the space marked with the code symbol of that station. It will be observed that record of the registry of lines at 31, for instance, might have been made just as Well and with equally satisfactory results. If new it be desired to change to station TV H N, the knob is quickly turned until the lines-register at 4:8 as previously determined.

. t will be rarticuh -l' invention permits o tions without de thereof. The 01: drawn with that I claim:

1. A. radio station selector adapted to 3' mounted upon a panel board eornprisine combination, a dial having indicated "ma adjacent to the periphery thereof, an indie cat from ang clenns new ,L c v adial divisions to correspond to aid marks, said indicator being 0;? ring term and having a circular lip d rected to said panel board, and fibrous material securing the indicator to the panel lZ-Oz and in proper relation to said dial, x fibrous material being disposed between said indicator and said panel board and lying: within said lip. 4

2. The herein described selector comprising a plate and attaching means for mount ing the same upon a panel hoard and adapted to lie between said plate and said board, said plate being of ring form and having a lip projecting toward the panel board for engaging and holding said attaehin means against lateral movement relative to said plate. I

3. The herein described selector comprising a plate and means for mounting the same upon a panel board including a sheet. of fibrous material adapted to lie between said plate and said panel board and having an adhesive substance upon the sides thereof to hold said plate at the one side and said panel board at the other, said. plate being of ring form and having lips formed along the edges thereof and turned toward said panel board, said sheet of fibrous material being adapted to lie Within said lips,

In testimony whereof I afiizt my n'ounted coaxially therewith and has .5
